HMC490
v03.0213 LOW NOISE AMPLIFIER -CHIP GaAs pHEMT MMIC LOW NOISE
HIGH IP3 AMPLIFIER, 12 -17 GHz
Typical Applications Features The HMC490 is ideal for use as either a LNA or driver
amplifier for: Noise Figure: 2 dB • Point-to-Point Radios Gain: 27 dB • Point-to-Multi-Point Radios Output IP3: +35 dBm • VSAT Supply Voltage: +5V • Military & Space 50 Ohm Matched Input/Output Output P1dB: +26 dBm Die Size: 2.78 x 1.46 x 0.1 mm Functional Diagram General Description
The HMC490 is a high dynamic range GaAs
PHEMT MMIC Low Noise Amplifier which operates
between 12 and 17 GHz. The HMC490 provides
27 dB of gain, 2 dB noise figure and an output IP3
of 35 dBm from a +5V supply voltage. The amplifier
chip can easily be integrated into Multi-Chip-Modules
(MCMs) due to its small size. All data is tested with
the chip in a 50 Ohm test fixture connected via
0.025mm (1 mil) diameter wire bonds of minimal length
0.31mm (12 mils). Electrical Specifications, TA = +25° C, Vdd = 5V, Idd = 200 mA*
